Why does my friend think she's Jesus Christ?

I'm sorry to say this but she is BIPOLAR. Angry; Mad; Sad; Happy. You can't believe anything that she really says. I think she is saying your plane is going to crash cause she wants to scare you and wants you to be sad to. She is jealous because your going to Florida and she is not. Stop all contact with her because she is making your life miserable. I'm sorry. Let her find her own help, if she wont seek that help your trying to help her get.
